l ELECTRIC RAT-EXTERMINATOR.

Specification of Letters Patent.

atcnted Sep t. 2, 1 913.

Application filed August 5, 1912. Serial No. 717,308.

To all 'Lo/tom t may concern:

Be it known that I, HARRY A. GnN'rzen, a citizen of the vUnited States,residing at New lhfighton, in the county of Beaver and State o tPennsylvania, have invented certain new and useful improvements inElectric Rattlxterminators; and l do hereby declare the lollowing to bea full, clear, and exact description ot the invention, such as willenable others skilled in the art to which it appertains to make and usethe same.

lhis invention relates to electa-ocutingl traps and has ttor an objectto provide a novel trap door which will electrocute and discl'large thedead rodents into an acid bath which will entirely consume the bodies.

iVith the above objects in view the invelr tion consists oit' certainnovel details of construction and combinationol. parts hereinaiter fullydescribed and claimed, it being understood that various modificationsmay be made in the minor details ot construction within the scope of theappended claim.

In the accompanying drawings forming part ot this speciiication:"Figurel is a longitudinal sectional View through the trap. Fig. 2 is ahorizontal sectional view taken on the line 2 2 Fig. 1. Fig. 3 is alongitudinal sectional view through the trap showingl the trap doorsprung. Fig. l is a cross sectional view taken on the line -1t Fig. 1.Fig. 5 a cross sectional View taken on the line 5 5 Fig. 1. Fig. 6 is avertical sectional riew taken on the line G-G Fig. 1. Fig. 7 is a planview ot' the source ot electrical energy. Fig. 8 is a diagrammatic Viewof the electrical connection.

teiterring now to the drawings in which like characters ciu referencedesignate similar parts, 10 designates a casing which is provided in thetop with an opening 11 which is normally closed by a trap door 12 formedof insulating material. A. tank 13 is carried within the easing and ispreferably tilled with a corrosive agent such as sulfuric acid or thelike to consume the bodies of rodents precipitated thereinto by the trapdoor into the tank.

A substantially rectangular trame 14; is tixed at one end to the trapdoor and is provided with a shaft 15 which is journaled in bearings 1Gthat depend from the top of the casing, the frame being further providedwith an arm 17 which is terminally equipped with a weight 18. Thismechanism pivotally supports the trap door in closed position, theweight counterbalancing the trap door and serving to return the same toclosed position a't'ter each operation.

rlhe trap door is provided on the top face with two interlitting copperplates 19 which are each composed ot" a plurality oil parallel fingers,the lingers being all insulated from each other by beingl preferablyembedded in the top itace oit' the trap door. One of the plates isconnected by a wire 20 to one secondary pole of an induction coil 2Q,and the other plate is connected by a conductor wire 21 to the othersecondary pole ot the induction coil Q2. The induction coil ispreferably inclosed in a casing Q3 which may be placed near the trap andcontains a plurality of battery cells 2l, the cells being connected inseries and one pole of the terminal. cell ot the series being connectedby a conductor wire 25 to one oit the primary poles ct the inductioncoil. rlhe other primary pole of the induction coil is connected by awire 26 to one pole 27 ot a knile switch 28 in the trap casing 10, theother pole QS) ot the kniie switch being' connected by a wire 3() to atrolley arm 31 which is pivotally connected at the upper ends to theunder side of the trap door by a hinge 32.

The trolley wheel contactsl with a metal shoe 31 which is connected by aconductor wire 35 to the other pole of the terminal battery cell asshown. A U-shaped housing 3G supports the shoe and extends beyond theends of the latter, the housing being carried npon the tops of legs 37secured to the bottom o1 the trap casing.

Upon a rodent advancing over the trap door to secure a lure which willbe presently described, the rodent must step upon both of the copperplates 19 and will complete a circuit between these plates, the hightension current instantly electrocuting the rodent. The weight oit therodent springs the trap door. The trolley `wheel runs oit' from the shoe34 at a certain point in the downward movement oit the trap door andbreaks the primary circuit of the induction coil, thereby breaking` thesecondary oit the induction coil. rlhe body then slides oli' from thetrap door into the tank and is consumed by the corrosive agent therein.It' the body becomes wedged between the t'ap door and top o'l. thecasing oit the trap, the primary circuit or battery circuit being brokenas above described will prevent a Waste ot' electricity `afterelectrocution of the rodent. Y

The lure or bait SS'is inclosed in a Wiremesh container 39 that issupported upon the top face of the tra-p casing at the rear of the trapdoor and is housed on two sides -by the side of a xl-shaped casing 40.The

casing is provided on the top with a. V- shaped hood 4-1 which preventsthe rodent from gaining access tothe bait through the top of the casing40.

1What is claimed, is

The combination of a counterloa-lenced trap door, bare electricalterminalsron the top face thereof, an induction coil operativelyconnected to said terminals, a trolley arm hingedly connected to thebottomV face of said trap door7 a slice contacting With said trolleyarm, and a source of electrical energy connected in series With saidtrolley arm, said shoe and the primary of said induction coil, saidtrolley arm being kadapted to run off of said shoe at a certain stageinthe dumping movement of said trap Vdoor Vincl break the primary circuitof said induction coil.

In testimony whereof, I ilix my signa*V OTTO C. GnosscLAss, GEO.SYMMoNDs.
